I think that you are asking about the gold 5 pound coin from Gibralter (KM#309b) commemorating D-Day. The coin is 36mm in diameter, weighs 39.83 grams and is 91.7% gold, giving it an AGW (Actual Gold Weight) of 1.1742 troy ounces. The front bears a crowned portrait of Queen Elizabeth the Second of Great Britain and the words "Elizabeth II" to the left and "GIBRALTER - 1994" to the right. The back has an image of a soldier, a sailor and a pilot above a tank, a plane and a ship, with the words "6 JUNE 1944 D-DAY" above and "5 POUNDS" below. 850 such coins were produced in gold, all in Proof condition. According to the Standard Catalog of World Coins, the value of the coin is US$1,150; however, since the gold value (as of June 2, 2011, with gold at US$1,536 per troy ounce) is about US$1,800, I would put the current value at around US$2,000.
Note that the coin was also produced in silver and in virenium (mintage of 5,000 each).
The first gold Fifty Pound coin issued by the Royal Mint was in 1987.

The English Pound has never been "gold covered". The British One Pound coin issued since 1984 is made from a nickel-brass alloy giving it a gold coloured appearance. The Sovereign coin, issued since 1817, has a face value of One Pound and is made from 22 carat gold.
The Royal Mint issued no gold Two Pound coins from 1938 to 1952 inclusive.
The British 1994 Two Pound coin is a commemorative issue for the 300th Anniversary of the Bank of England. They only have any value if they are in mint uncirculated condition, or are Proof coins. In addition to nickel-brass, the Royal Mint usually mints the Proof coins in silver and gold as well, but the values of the Proof coins are reflected in the initial purchase price which would be directly related to the market price of gold and silver at any given time.
